INTERCHANGEABLE ANTI-SLIP SHOE SOLE ATTACHMENT Filed March 5, 1957ATTORNEYS United States Patent INTERCHANGEABLE ANT I-SLlP SHOE SOLEATTACHNIENT Application The present invention relates to attachable anddetachable anti-slip devices for shoe soles having interchangeableanti-slip surfaces.

The primary object of the invention is to provide an interchangeableanti-slip surface detachably secured to a shoe in underlying relation tothe sole so as to decrease the slipping qualities of the sole.

Another object of the invention is to provide an interchangeableanti-slip member having a detachable slide fastener construction forsecuring the anti-slip material to the remainder of the device.

A further object of the invention is to provide a device of the classdescribed above which is inexpensive to manufacture, simple to apply anduse, and which will materially increase the safety of the user whenwalking on slippery surfaces.

Other objects and advantages will become apparent'in the followingspecification when considered in the light of the attached drawings, inwhich:

Figure 1 is a top plan view of the invention.

Figure 2 is a side elevation of the invention.

Figure 3 is a transverse cross-section taken along the line 3-3 ofFigure 1, looking in the direction of the arrows.

Figure 4 is a fragmentary bottom plan view illustrating the anti-slipsurface.

Referring now to the drawings in detail wherein like referencecharacters indicate like parts throughout the several figures, thereference numeral indicates generally an interchangeable anti-slip shoesole attachment constructed in "accordance with the invention.

The attachment 10 comprises an elastic band 11 which is folded onitself, as indicated in Figure 3, and sewed together by stitching 12with the tape 13 on one side of a slide fastener 14 securedtherebetween.

A panel 15 having the same general shape and size as a shoe sole issecured by any suitable means, such as stitching 16, to the tape slider18 is arranged on the slide fastener 14 so as to separate the tapes 13and 17 to detach the panel 15 from the band 11.

The panel 15 comprises an inner portion 19 formed of fabric or othersuitable material, a central fabric back 20, and an abrasive coating 21secured to the fabric back 20 by suitable adhesive means.

In the use and operation of the invention, the elastic band 11 isengaged over the sides of the shoe with the panel 15 in position beneaththe shoe sole so that the abrasive surface 21 will be positioned forengagement with the walking surface. When the abrasive surface 21becomes exhausted, it can be replaced by separating the slide fastener14 with the slider 18 and applying a new panel 15 by means of a halfslide fastener thereon.

It should be obvious that the elastic band 11 makes the application andremoval of the attachment 10 from the shoe exceedingly easy so that onreaching areas such as hardwood floors which would be scratched by theabrasive surface 21, the attachment 10 can be quickly removed from theshoe.

Having thus described the preferred embodiment of the invention, itshould be understood that numerous structural modifications andadaptations may be resorted to without departing from the scope of theappended claim.

What is claimed is:

An interchangeable, anti-slip shoe sole attachment comprising an endlesselasticjband folded on itself, a flexible fabric material panel havingthe configuration of a shoe sole, an abrasive coating on the bottom ofsaid panel, an elongated separable slide fastener, and a slider, oneside of said slide fastener being fixedly secured to the upper portionof said panel adjacent the marginal edges thereof, the other side ofsaid slide fastener being secured by stitches between the folded sidesof said elastic band whereby said panel is detachably secured to saidband by said fastener so that the panel may be replaced when it has wornout.
